Oblicz polecałkowite granaiastosłupa . Dane : H = 11dm a = 10 dm b = 5 dm h = 12 dm c = 13 dm .
Pp=(a+b)·h/2
Pp=(10dm+5dm)·12dm/2=90dm²
Ppc=2Pp+Pb
Ppc=2·90dm²+10dm·11dm+5dm·11dm+12dm·11dm+13dm·11dm=
=180dm²+110dm²+55dm²+132dm²+143dm²=620dm²
Odp.: Pole powierzchni całkowitej graniastosłupa wynosi 620dm².
Pp=(a+b) *h /2
Pp=(10dm+5dm)*12dm /2=15dm*12dm/ 2 = 180dm/2= 90dm²
Ppc=2*90dm²+10dm*11dm+5dm*11dm+12dm*11dm+13dm*11dm
Ppc=180dm²+110dm²+55dm²+132dm²+143dm²=620dm²
